Reason #3

Non-googleable questions

We have a very high focus on the quality of questions that test for on-the-job skills. Every question is non-googleable and we have a very high bar for the level of subject matter experts we onboard to create these questions. We have crawlers to check if any of the questions are leaked online. If/ when a question gets leaked, we get an alert. We change the question for you & let you know.

How we design questions

These are just a small sample from our library of 10,000+ questions. The actual questions on this Microsoft Power BI Test will be non-googleable.

Data Filtering
Report Development
M Language
Data Visualization
Solve
You are creating a Power BI report where users need to dynamically filter data based on a range of dates. The report has a Sales table with columns Date, ProductID, and Amount. You decide to use a Power Query parameter to allow users to select a start and end date, which will then filter the Sales table accordingly. The parameter is named DateRange and has a type of List. You need to write a Power Query M formula to filter the Sales table based on the selected date range. The DateRange parameter contains two dates: the first item is the start date, and the second item is the end date. How should the M formula be structured to achieve this functionality?
A: Table.SelectRows(Sales, each [Date] >= DateRange{0} and [Date] <= DateRange{1})

B: Sales{[Date] >= DateRange{0}, [Date] <= DateRange{1}}

C: Table.FilterRows(Sales, each [Date] >= List.First(DateRange) and [Date] <= List.Last(DateRange))

D: Table.SelectRows(Sales, each [Date] >= List.First(DateRange) and [Date] <= List.Last(DateRange))

E: Filter.Table(Sales, [Date] >= DateRange{0}, [Date] <= DateRange{1})

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Microsoft Power BI Test in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.

1 click candidate invites

Email invites: You can send candidates an email invite to the Microsoft Power BI Test from your dashboard by entering their email address.

Public link: You can create a public link for each test that you can share with candidates.

API or integrations: You can invite candidates directly from your ATS by using our pre-built integrations with popular ATS systems or building a custom integration with your in-house ATS.

How do I interpret test scores?

The primary thing to keep in mind is that an assessment is an elimination tool, not a selection tool. A skills assessment is optimized to help you eliminate candidates who are not technically qualified for the role, it is not optimized to help you find the best candidate for the role. So the ideal way to use an assessment is to decide a threshold score (typically 55%, we help you benchmark) and invite all candidates who score above the threshold for the next rounds of interview.

What experience level can I use this test for?

Each Adaface assessment is customized to your job description/ ideal candidate persona (our subject matter experts will pick the right questions for your assessment from our library of 10000+ questions). This assessment can be customized for any experience level.
